First of all the plants look great,Healthy ,vibrant , full, But I dont like the containers ,to small for what you have there so young , is there 1 plant per container hope so , next soil looks dry and compacted ,so i think a transplant into larger pots with a little extra perlite ,with B1 let sit 3-4 days and flip the switch they will go nuts ,1to 1.5 inch a day with 1000 watt . also I veg under a set of 3 t5 fixtures for 4-6 weeks from clones 24 hours in RH dome aathe beginning ,when rooted "rapid rooters" 10 -14 days transplant to 6 inch pot and go 18/6 at about 45 -50 days transplant 6inch into large 3-5 gallon pot then they are ready to go to flower when my other girls are finished in the flower room ,has worked well lower power bills because of the t5 vegging and get great plants for veg ,very full robust not lanky at all.My 2 cents,Happy Farming ,Cajun::animbong:
